  • Patent number: 9083832
    Abstract: A light guide inserted into an inclined groove is disposed so as to partially overlap with a lens unit that is fitted into a concave groove disposed parallel to the inclined groove when seen in a plan view, to regulate the separation of the lens unit from the concave groove and hold the lens unit in an insertion state by the light guide. Therefore, a fixing unit such as an adhesive agent is not required in fixedly disposing the light guide and the lens unit at a predetermined position of a frame, and a CIS module is assembled without using an adhesive agent, thereby allowing the CIS module that is easily disassembled when being discarded and that improves recycling efficiency to be provided.

  • Patent number: 8908239
    Abstract: Since a light emitting surface in a cross section perpendicular to the longitudinal direction of a light guide is formed to have a smaller width than a reflecting surface, light of an LED, which is incident from an end surface of the light guide and is scattered throughout the entirety of the longitudinal direction in the reflecting surface, is condensed toward the light emitting surface, and is then emitted in the form of a band toward a document from the light emitting surface. Therefore, it is possible to provide a CIS module including an illumination unit having a new configuration capable of illuminating a portion where the document and an optical axis of the lens array included in the lens unit intersect, in the form of a band with high efficiency using the illumination unit.
